Pfizer and Moderna's legal battle over their rival COVID-19 vaccines will continue after London's High Court on Wednesday gave Pfizer permission to take the case to the Court of Appeal. Pfizer and BioNTech sued Moderna in September 2022, seeking to revoke Moderna's two patents. Additionally, Moderna faced criticism from a U.K. trade group for offering children $2,000 to participate in a COVID-19 trial, which was deemed to have brought discredit upon the pharmaceutical industry. The legal dispute is described as a multimillion-pound battle.
